APPARATUS FOR CUTTING CLAY PRODUCTS.

Application filed February 13, 1914.

To all whom it may concern Be it known that I, DAVIS BROWN, a citizen of the United States, and resident of Bucyrus, county of Crawford, State of Ohio, have invented an Improvement in Apparatus for Cutting Clay Products, of which the following description, in connection with the accompanying drawings, is a specification. like letters on the drawings representing like parts.

My present invention is an improved process of cutting clay products as the same issue from a die, and may be employed either with automatically rotating wire cutters, or otherwise. In cutting clay products, particularly brick and hollow tile, from a stream of brick material as the same issues from the die of a brick making machine, it has been customary to arrange the wire cutting reel so that it will pass through the brick stream, severing the same into separate articles in a well known manner. This former process, however, caused a roughened surface to be thrown up or raised on the sides of the brick stream, the wire cutting a smooth, even and clean edge only onthe top of the material, where the wire initiated the cut. Furthermore, as the wire could not pass below the moving table carrying the brick stream, a further unevenness was left on the lower surface of the article cut. In the manufacture of hollow brick and tile also, the partitions in the interior of the brick being comparatively thin and soft,

were apt to be deformed by the cutting wire passing therethrough, and an objectionable ridge or bead was raised around the entire edge of the article cut, interfering with its smooth and even setting in a wall.

In order to obviate the difliculties above noted, I have discovered that by having the die on the brick or tile machine arranged to present a corner uppermost, and a carrying table cooperating therewith to receive, support and carry the brick material in this angular position, 2'. c. with a corner uppermost, and then subjecting the material to the action of the cutting wire, that the difliculties heretofore existing were obviated, and that a smooth, even, clean cut was afforded on the two sides of the brick or tile slanting from such uppermost corner. Furthermore the partitions within a hollow tile, withstanding the action of the cutting wire in an inclined or slanting position, as distin- Patented Nov. 6, i917. erial No. 818,476.

guished from the former arrangement'of a flat, horizontal impact, prevented the dcforming of the partitions, and also afforded a clean continuous cut. Each end of the brick or tile was therefore formed perfectly smooth, and by elevating the carrier supports slightly and permitting the wire to pass through slots therein and extend entirely below the bottom-most corner of the material, a complete, clean out throughout the entire extent of the stream is afforded. This process is especially-important in the handling of tender clays and in the manufacture of hollow tile having a plurality of internal partitions. In carrying out the process, I have employed a carrying table of the general, type shown in United States Patent No. 537,808,:dated April 16,1895, with my novel features embodied therein.

Referring to the drawings, showing my improved type of apparatus suitable for carrying out my process of cutting clay proclucts,

Figure 1 illustrates in side View, and partly in section, a wire cutter and carrier; and

Fig. 2 being an enlarged end view, partly in cross section, with a cutting wire having completed a cut to sever an article from the brick stream. 1

In carrying out my present process, I arrange the brick die 1, partially illustrated in Fig. 1 and shown in end view in Fig. 2, at an angle, so as to form the stream of brick material 52 with a corner uppermost, presenting a side face 3 and end face 4 at an angle to the action of the cutting wire.

In order to receive the brick stream 2 in this angular relation, I provide the carrier, indicated generally at 5, having a series of platens6 and 7, with raised and tilted receiving portions 8 and 9 (see Fig. 2). These raised portions 8 and 9 may be formed from a single sheet of plate material bent into'suitable form to receive the brick stream 2 and with legs or extensions 10 and 11 respectively bolted to the carrying platens in any suitable manner. An intermediate support or leg 12 may also be provided, if desired, particularly when heavy work is contemplated, which serves to hold the faces 8 and 9 in firm and rigid position and to support the same sufliciently above the platens 6 and 7 to enable the cutting wire to sweep below the lowermost corner of the brick, and make a complete, clean, shearing out. It will. be readily understood that I may provide single platens suitable for the length of a brick or tile being made, or may utilize double platens for each length of brick r tile,in Fig. 1 a pair of such double platens 6 and 7 being illustrated, each adapted to support a single length of tile. These platens 6' and 7 are joined together and used on roll (or slides) so as to easily swing around the ends of the carrier 5 in a manner generally similar to that explained in said prior patent, and as this feature does not constitute a part of my present invention it need not be explained in further detail. On each platen or pair of platens where a pair is provided to carry a single length of article cut, is aliixed a guidepost 1 to rece 'e and guide the cutting wire let on each pair of gates 15 ca ried by the cutting reel 16, in a well known manr r, as will be readily understood on reference to the drawings. A. tension and adjusting device 17 for the wire 14 is illustrated in Fig. 2, and is of any suitable or usual type.

In operation the stream of brick material 2 issues from the die 1 with a corner uppermost, and is received by the moving platens 6 and 7 on the carrier 5, the platens conducting the stream 2 under the cutting reel 16, the cutting wire 1% following down alom the guides 13 and forming the stream into separate articles. The action of the cutting wire 14:, as it moves through the brick material, is a sliding or shearing cut, starting in the uppermost corner and sweep ing diagonally along the inclined faces 3 and 4:, thus making an even, clean cut, and not throwing up any bead or roughened edge along these surfaces. its thev supports 8 and 9 are raised above the surface of the carrying platens 6 and 7, the wire is enabled to pass down completely through the stream of material making a clean cut. The several partitions within hollow tile when this is being made, will receive the action of the cutting wire 14 in the same shearing, diagonal and continuous cutting manner as that afforded by the inclined faces 3 and 4-.

This enables thin partitions to be cleanly out without being deformed or distorted in the least, and furthermore insures an even, unroughened surface throughout at least two sides of the brick and tile, and of each partition in hollow tile work. The importance and advantages of a cleaner cutthus obtained, particularly on the two inclined faces, will be readily appreciated; I have found that the action of the wire in passing from a corner diagonally along the inclined faces affords a much sharper and smoother and cleaner cut on the under faces abutting on the supports 6 and 7, as well as on the under faces of the partitions in hollow tile work, than was formerly possible where the wire cut squarely and came out of the under face (or faces) of the partitions in a square manner. Thus, I am enabled to make a cleaner, smoother and sharper cuton the brick or hollow tile material, not only on the two upstanding faces 3 and L, but on the opposite lower faces where the cutting wire emerges from the material as well.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

Apparatus for automatically cutting angularly sided clay products, comprising a brick machine die angularly positioned with relation to the stream of brick material, a carrier arranged to receive and carry the angularly sided stream of brick material with one angle uppermost and a cutting reel adapted to make a diagonal slicing cut relatively to the faces of the clay column across said stream of brick material to sever an article therefrom by horizontally positioned cutting wires moving substantially in a vertical plane and first engaging the angularly held stream of brick material on the uppermost edge.

In testimony whereof, I have signed my name to this specification, in the presence of twov subscribing witnesses.
